SUSPENSION DEVICE FOB OITTBOARD MOTORS.

Application filed July 3, 1813. Serial No. 777,153.

To all whom it may concern:

Be it known that we, CARL "Bxmr and Osciu: Wiicriun Hum", subjects of the King of Sweden, and residents of 1 I11- edalsgaten, Stockholm, in the Kingdom of Sweden, engineers, have invented certain new and useful Improvements in Suspension Devices for Outboard Motors, of which the following is a, specification, references being made to the accompanying drawings.

The present invention relates to outboard motor suspension devices of the v type in which the motor may turn in. bows, sleeves, or the like, surrounding the motor cylinder or cylinders, or 21 art or parts connected with the motor cylinder, or the motor cyl inders;

The invention, which is specially intended for larger outboard motors, comprises such an arrangement of the said suspension devices that the motor itself can be readily removed from the suspension device (which latter remains fixed to the boat) and parts carried by the device, such as the propeller and parts belongingto it or deseendin to it, and that the whole can be mounte on the boat with greater ease, and be more conveniently accommodlted in it, when dismounted.

The invention is cheructerized mainly by the fact that a part, c. g. a frame, a support, or the like, including a sleeve (*oi sleeves) or the like surrounding the motor shaft, and which part adjustable relatively to the clamp by means of which the suspension device issecurely fixed to the host, is guided by the clamping members engaging the motor cylinders and the ports placed in the said clamping members in such a manner that the motor shaft or its bearing. can be 'insertedinto the sleeve (or sleeves) no matter what position the frame etc. occupies relatively to the clamp (or corresponding part).

in the accompanying drawings is shown by way of example a. suspension device can ricd out in accordance with this invention.

Figures 1 and Z'show the suspension de rice with a motor pinned in it. seen from in front and from one end respectively, while Fig. 3 shows a section taken along the line A--B in Fig. l (the motor cylin- (her is not shown in section). Fig. 4 shows a longitudinal section of slcevennd ports in it.

Specification of Letters Patent.

Patented Nov. 24;, 1914.

The invention is shown applied, by way; of example, to a so-culled balance motor,

1'. e. a. motor with two cylinders situated so us to oppose each other. The c linders 1 are surrounded by clumping ows 2. These clamping bows 2- are carried b arms 3, extending from a clamp 4,which 1s fixed to the bout with the aid of bow-shaped parts and clamping screws 5 placed in them. An outer sleeve 6, which surrounds the motor shaft 1" forms the central part of a frame consisting of arms 7 extending obliquely upward from the lower end-of the sleeve, and arms 8, projectin horizontally from the upper end-of t e sleeve. The arms 7 and 8 10m and are prolonged'by arms 9 extending obliquely u ward and outward. The lowerparts o the clamping bows 2, from which parts the arms 3 do;

soend, are not in immediate contact withthe cylinders 1, but betweenthem and the cylinders there are arched spaces1Q,.in-

which the correspondingly formed free ends 9 of the arms 9 are jammed whereby the motor is firmly kept in the said bows.

T he breadth of the ends 9 is so adjusted that the ends can occupy dilferent positions in the spaces 10, i. e. that the frame I, 8, 9 can be adjusted to different. angles relatively to the clamp 4. Mor ver, .the arrangement is such that the cen er line of the frame sleeve fitcuts the center line. common to the two slumping bows. The consequence of this is that the motor shaft 1", or the bearihg 11 surrounding it, can always he inserted downward in the frame sleeve 6 with any usual shape of stern, i. e. no matter what the relative position of the frame 7, 8, and 9 and the clamping piece 4 may be... When the motor shaft l is inserted in the frame sleeve 6, it becomes, with the aid of :1 couplingdevice in the said sleeve, coupled together with a shaft 12-, which forms an extension of said motor shaft, and which shaft is with the aid of n gearing coupled tothe propeller shaft.

The coupling device in question, which must admit of the shaft IZbeing raised and lowered in order to adjust the propeller to the desired height, may suitably be coir structed in the following manner. The frame sleeve 6 surrounds a sleeve 14 (the so-called conveying sleeve which at each of its ends is provided with an in wardly directed wedge 15 and 16 respectively. (Instead of two edges, there may ion obviously be only one, extending fromthe 7 upper end of the conveyin sleeve to its lower end). The upper we ge 15 enters a groove 17, arranged in the motor shaft,

while the lower wedge 16 enters a groove 18 arranged in the prolongation shaft 12.

Between'the frame sleeve 6 and the conveying sleeve 14 there is a-sleeve 19, which 14 is firmly connected with the motor shaft 1' with the aid of a screw 1 1%, The frame sleeve 6 is slotted at its lower end and has a screw 22 for clamping the'said end around the intermediate sleeve 19. When v the screw 22 has been loosened, the intermediate sleeve 19 and the parts connected with it, as well as the propeller, can be raised or lowered in a vertical direction (and also turned, if required), the wedge groove 18 then being moved relatively to the wedge 16. \Vhen the propeller has thus been adjusted to the desired height (itis shown in Fig. 1 in its highest position), the lower end of the frame sleeve is again tightened around the intermediate sleeve 19. The steering of the boat is effected, according to the drawings, by turning a sleeve 23 surrounding the intermediate sleeve 19 and on which sleeve 23 the rudder is fixed.

Having now described our invention, what we claim as new and desire to secure by Letters Patent is; l

1. In a device of the 'characterdescribed, the combination of a boat, a motor therefor having an extended motor shaft, a clamp clampin attachable to said boat and having blamp- 7 ing means for holding said motor, and a motor support including a sleeve embracing said motor shaft, said support having parts adapted to be clamped b said clamping means between them and t e motor.

2. In a device or the character described,

' the combination of a boat, a motor therefor the combination of a boat, a motor therefor having opposed cylinders and an extended motor shaft, a clamp attachable to said boat and havinF a pair of oppositely arranged substantia ly annular clamping means adapted to encircle the said cylinders, there being a 5 race between each cylinder and the means encircling the same, and a substantially triangular frame embodying a central sleeve embracing the motor shaft and short, laterally projecting, arms adapted to be held in the space between the said cylinders and the said clamping means.

In witness whereof we here hereunto set our hands in presence of two witnesses.
